but this code gives me the following error.

"Fatal error: Call to a member function getAttributeNode() on a non-object in D:\wamp\www\ReadXml\new.php on line 35"

<?php

$xml = new DOMDocument();

$doc->recover = true;

$xml->load('test.xml');

$node = $xml->getElementsByTagName('*');

$nodename = "";

$node_name = array();

$att = "";

$attr_name = "";

$attr_value = "";

foreach($node as $value)

{

echo "<HTML><Head>";

echo "<title> Getting Attribute Example</title>";

echo "</Head><body>";

echo "Node Name is :".$value->nodeName;

echo " </body></HTML>";

$nodename = $value->nodeName;

$node_name = $xml->getElementsByTagName('$nodename')->item(0);

echo $nodename;

$att = $node_name->getAttributeNode('name'); //Line No 35

echo "<HTML><Head>";

echo "<title> Getting Attribute Example</title>";

echo "</Head><body>";

echo "Node Name is :".$att->name;

echo " Attribute Value is :".$att->value;

echo " </body></HTML>";

$attr_name = $att->name;

$attr_value = '"' . $att->value . '"';

$nodename->removeAttributeNode('$attr_name');

$nodename->setAttributeNode(new DOMAttr('$attr_name', 'hello'));

$nodename->setAttribute(new DOMAttr('$attr_name', '$attr_name'));

$xml->save('temp2.xml');

}

?>

Remove the single quotes from line 33, there is no need to put variables in quotes.

Remember that a variable in single quotes will never work because php does not recognise variables in single quotes. Php treats the variable as a string literal.
